I don't think you can do what you want to do. When I first bought my current truck, used, my Tri-Pac was a total disaster, and I wound up taking it in to my local Detroit TK shop. The parameters were set on a laptop with a program like Navistar uses, not something I believe you can do in the cab, as it was pretty detailed. I have owned quite a few of these units too... Should not take the tech more than 5 minutes to do the job if he knows what he is doing.
